From TORK blog
Following our previous post about a nice hidden tip for catkin-tools, here’s another one.
When finishes compilation, `catkin build` shows a pop-up window at
the top-right on your screen (if you’re on Ubuntu Linux), which
indicates `Build Finished` or `Build Failed`. This is nice in that you
can work on another windows without payting attention to catkin’s
progress. Caveat is, though, that “Finished” and “Failed” aren’t that
obviously differentiating whatsoever.
With the newer version of catkin-tools, 0.4.3 or higher, the window
pops up with a distinguishable colors; Green for success and red for
failure.
This little but significantly effective change is done by our TORK
associates again. The change was made swiftly and neatly as it has
always been in the opensource software community.
